Abstract
The utility model provides a hoisting accessory for large -scale pressure steel pipe turn -over includes the girder, and support the bracing piece of girder is equipped with at least two and lifts by crane the part on the girder, the part that lifts by crane include the lifting hook, the lifting rope couples together the lifting hook through the assembly pulley with drive device. The utility model has the advantages of, be applicable to the narrow and small environment that lifts by crane of spatial position, and have economical and practical, safe and reliable, simple to operate, easily operation.
Description
Technical field
This utility model relates to a kind of boom hoisting for penstock turn-over, is particularly well-suited to the boom hoisting of locus narrow and small penstock turn-over.
Background technology
Ultra-large type penstock turn-over is it is said that in general, use two truck cranes to lift turn-over and apply more, but penstock installation period is longer, and it is the highest that rent-a-car hangs turn-over cost.In the case of the duration is more nervous, there will be the situation that truck crane equipment is not enough simultaneously.If narrow and small for locus, penstock turn-over position, hole, truck crane cannot erect-position also result in steel pipe cannot the situation of turn-over.Based on above reason, a kind of boom hoisting for large-scale penstock turn-over arises at the historic moment, and this device fully meets whole requirements of steel pipe turn-over.
Summary of the invention
This utility model provides a kind of boom hoisting for large-scale penstock turn-over, it is applicable to the narrow and small lifting in locus environment, and there is the advantages such as economical and practical, safe and reliable, easy for installation, easily operated, the efficiency that ultra-large type penstock is installed can be increased substantially
Realizing the technical solution of the utility model is, a kind of boom hoisting for large-scale penstock turn-over includes girder, and the support bar of support girder, is provided with at least two lifting part on girder；
Described lifting part includes suspension hook, and suspension hook is coupled together with driving equipment by lifting rope by assembly pulley.
Further, being provided with buffer bar, buffer bar front end arcuate groove on described support bar, arcuate groove surface is provided with cushion pad.
It is also possible that buffer bar is connected on support bar by sliding shoe, support bar is provided with sliding tray, and sliding shoe embeds in sliding tray, and buffer bar links on sliding shoe.
It is also possible that sliding shoe is connected with pneumatic means, pneumatic means drives sliding shoe to slide in sliding tray.Further, pressure inductor is located on expansion link.
The utility model has the advantages that, without automobile loop wheel machine saved cost, to construction field use less demanding, work efficiency is high.

Detailed description of the invention
In Fig. 1, a kind of boom hoisting for large-scale penstock turn-over includes girder 1, and the support bar 2 of support girder 1, girder 1 is provided with two lifting part 3, one of them lifting part 3 is main Heave Here, main Heave Here lifting for large-scale penstock and hoisting, and plays the steel pipe weight that lift is 1.25 times；
Another lifting part 3 is secondary Heave Here, and the lifting and transferring for large-scale penstock of secondary Heave Here, the power of transferring is the half of the steel pipe weight of 1.25 times.
Lifting part 3 includes suspension hook, and lifting rope 4 is preferred with driving equipment 6(by suspension hook by assembly pulley 5, drives equipment 6 for hoisting machine) couple together.
Method of work, 1. must carry out stress test according to 1.25 times of loads after this device context installation, and defective forbidding uses stress test.
2. large-scale penstock utilizes flat car transport to being used under the boom hoisting of large-scale penstock turn-over, uses main Heave Here, secondary Heave Here to lift steel pipe, backed off after random flat car of unloading.
The most main Heave Here hoists large-scale penstock, scale-up version penstock under secondary Heave Here.
4. treating that secondary Heave Here steel wire rope does not stresses, during main Heave Here vertical lifting steel pipe, main suspension centre falls to being placed on transport trolley by steel pipe and reinforce fixing.
Preferably, such as Fig. 2, in 3, described support bar 1 is provided with buffer bar 7, buffer bar 7 front end arcuate groove, arcuate groove surface is provided with cushion pad, and buffer bar 7 is connected on support bar 1 by sliding shoe 8, and support bar 1 is provided with sliding tray 9, sliding shoe 8 embeds in sliding tray 9, and buffer bar 7 links on sliding shoe 8.When large-scale penstock turn-over, buffer bar 7 front end is made to contact with large-scale penstock surface with the part of cushion pad, it is possible to prevent large-scale penstock to horizontally slip, overturn then as large-scale penstock, power is passed and forwards sliding shoe 8 to by buffer bar 7, and make sliding shoe 8 slide in sliding tray 9, thus ensure smoothly large-scale penstock to be realized upset.
Further preferred, sliding shoe 8 is connected with pneumatic means, and pneumatic means drives sliding shoe 8 to slide in sliding tray 9, during work, make sliding shoe 8 slide smoothly in sliding tray 9 by pneumatic means, thus realize controlling to the turn-over process of large-scale penstock by buffer bar 7.
